A stampede of zealous fans eager to greet Megumi who is to perform a concert on the oceanliner being maneuvered into the port in preparation for docking means bad news for both Posi and Nega as the two cats are lost in the lurch during the hullabaloo; while Nega divides his energies between nursing his headache and getting his bearings as he computes his next move, a girl named Catherine successfully makes her escape from the ship much to her nanny's frustration. After explaining her prologue and her objective for being in Japan, Catherine sets course for her childhood home with Nega who tries to explain Posi the situation he is in; while Nega enjoys Catherine taking care of him in spite of the rough ride, Yuu is forced to suspend the search when it comes time for her to do her thing as Creamy Mami. The magic dream box now in hand thanks to some well-timed moves and cooperative circumstances, the problem now becomes how to smuggle Catherine back in under the nose of her very frustrated nanny; after Yuu leads the nanny on a wild goose chase, Nega and Posi explain Catherine the importance of believing in her own dreams and ultimately creating far grander dreams that transcend what can be kept inside a box as the ship sets sail.
